Random sampling is when you select a random group of people for something.
Ex. Out of a population of 259,096 people, a random sample of 400 people are choosen.
44-2x=x-10
subtract 44 from both sides
-2x= x-54
subtract x from both sides
-3x= -54
divide by -3
x= 18
square root of 18= 4.24
in radical form 3 square root of 2
hope this helps
